A NUMERICAL INVESTIGATION ON THE STRESS-BALANCED SPUR GEAR PAIRS

Abstract

Involute spur gears are key machine elements for power transmission in various industrial sectors. During power transmission, the teeth are subjected to high stresses. Many design modifications are used to reduce these stresses, such as increasing the drive side pressure angle and profile shifting factor. These modifications change the contact ratio and center distance of the gear pair. Changing the tooth thickness is another solution to reduce stress. Because there is a difference in the number of teeth between the pinion and the gear, the pinion stress levels are higher than the gear for the same gear parameters. The tooth thickness value in the tooth thickness on the pitch circle is equal to 0.5xπm for both pinion and gear as standard. Stress compensation can be achieved by increasing this thickness at the pinion and decreasing it at the same rate at the gear. In this study, first of all, 3D designs of gears with non-standard thickness were created in CATIA and finite element analyzes were performed to obtain tooth thickness values that create equal root stresses for pinion and gear with various tooth numbers. According to preliminary results, tooth deformation and stress has a linear relationship with tooth thickness value, nearly.
